Re: extreme birdsong; last push on project

I'm definitely interested!

Really enjoying being able to "chunk" larger groups of audio and then go in for fine-tuning later. My earlier method looks pretty neurotic in retrospect. :)

Yeah, well, . . . I'm not happy with tweetie-pie - has become a rusty bike chain . . . . I also removed some more White Noise

http://www.dvinfo.net/forum/attachme...1&d=1442409094

Of course, as I started cleaning-up I came across other artifacts.

I also added some SFx - iZo Ozone5 "Dramatic Width and Open Up Mid-Side" to a Brush-ed Selection - neat! Gonna use that again.

Grazie

Re: extreme birdsong; last push on project

I've just listened to the original audio file.

Honestly, just tell them that the audio is terrible and to go back and do a re-shoot. If they can't then it's their problem - otherwise we're effectively subsidising their cheap sense of reality.

Re: extreme birdsong; last push on project

Andrew...lol, if i had my time machine, I would go back in time and ream out the camera man (it was filmed 13 years ago). But also, as someone that has done a 1-man-shoot-on-a-budget for near-impossible documentary-filming situations, I can empathize. His poor work inspired my low-budget multi-microphone vector approach to mic'ing large groups.

The good news is, I learned a lot. About pop and crackles, clicks, how to remove lots of coughs and sniffs (the camera man not only laughed a lot, but sniffed even more) and those birds...

Graham: I found that the birds are best treated with RX4s attenuation from .9 -> 2.0. The solo ones can be totally removed, where the long stretches you worked on can be nicely blended into the voice...better than your bike chain at least ! :P

I ended up using a simple technique:

x26 gain on every clip in the film
apply EBU loudness over the whole clip
apply decrackle over the whole clip
Low and high cuts, 90db and a 10-14k db fade-away

From there I went in and manually removed any further clicks, coughs, sniffs, and birds. With RX4s attenuation, partials-spectral-repair-tool, declicker and occasionally just de-gaining. For hums I don't know how to identify and nail exact frequencies as well with RX4 (it tends to want to take out multi-bands) so I used Audacity to seek out hums and removed those to a greater or lesser extent.

Here's my final cut of the horrendous clip in question:

thanks for all the help...about a week away from finishing this documentary I've been working on for two years :)

You're welcome.

As to the HUM remover, I've found that the multiple harmonics can and do work very well; I can also de-group the harmonics; I also use the Spectrum Analyzer to nail a particular Harmo:http://www.dvinfo.net/forum/attachme...1&d=1442818399

I like your results and still think that RX is just plain VooDoo! - Oh, that's IT Engineer Terminology.

Grazie

Izotope RX is powered by magical electronic smoke. :-D

Graham - thanks for pointing out the analyzer and the harmonics...simplified my workflow

Re: extreme birdsong; last push on project

While you're at it...Graham, could you tell me if there's a key-command in RX4 that stops the playback at the last place the live-play ended at? For me, spacebar returns to the last place I clicked the cursor, and enter starts at the start of the sample.

The RX solution/way is not intuitive. At the moment you/we have SPACEBAR for PLAY, that plays and then RETURNS to the same place. In RX we need to use a "TOGGLE" command to stop this happening, and that is Ctrl+R.

The SPACE Bar plays and returns, and CTRL+R stops this Return happening. Now, when we WANT to revert to the PLAY from start position to play again, we need to, again, press Ctrl+R. I think this is clunky and unnecessary User control.
